Iridium communications owns and operates the constellation additionally selling equipment and access to its services it was originally conceived by bary bertiger raymond j.

Iridium satellite frequency range.

L band in the range from 1621 35 to 1626 5 mhz used for both uplink and downlink. Formerly iridium satellite llc is a publicly traded american company headquartered in mclean virginia iridium operates the iridium satellite constellation a system of 66 active satellites and 9 spares in space used for worldwide voice and data communication from hand held satellite phones and other transceiver units. Between iridium phone terminal and iridium satellite. This is the l band uplink downlink for the low earth orbit iridium satellite constellation.

Leopold and ken peterson in late 1987 in 1988. I q raw recording. With communications solutions ranging from satellite phones to broadband terminals iridium is trusted by more than a million mariners pilots humanitarians first responders and governments around the world. Only iridium offers truly global communications through a constellation of 66 crosslinked leo satellites.

The link between the iridium satellite and a user typically operates at a 2 4kbps data rate for voice communications up to 64kbps for l band handset data services short burst data and 512kbit s to 1 5mbit s when using an iridium openport terminal servicing customers with a need for more data. Iridium satellite frequency description. 1616 mhz 1626 5 mhz. 23 18 to 23 38 ghz.

The satellites transmit in the l band at carrier frequencies in the range of 1616 1626 5 mhz using quadrature phase shift keying qpsk with a symbol rate of 25 000 symbols per second. The iridium satellite constellation provides l band voice and data information coverage to satellite phones pagers and integrated transceivers over the entire earth surface. The iridium 9602 transceiver designed to be integrated into a wireless data application with other host system hardware and software provides a complete satellite iot data solution for your application. The iridium satellite system uses l band transponders to communicate with the ground based users with frequencies in the band 1616 1626 5 mhz while the backhaul to the terrestrial gateways is in the band between 29 1 and 29 3 ghz for the up link and in the band between 19 1 and 19 6 ghz for the downlink.

Between two iridium satellites. With the variety of satellite frequency bands that can be used designations have been developed so that they can be referred to easily. 1616 mhz 1626 5 mhz.
